26、describes requirements for bar-code labels on distribution transformers and step-voltage regulators when specified by users. The intent of the bar coding described in this standard is to provide basic identification information for a transformer or step-voltage regulator and as an aid in linking to
27、more detailed information about the transformer or regulator that may reside in a utility companys central database. This standard describes requirements for a permanent bar-code label that may be part of the nameplate as well as for a temporary bar-code label intended primarily for material managem
28、ent purposes. Requirements described in this standard address bar-code label format, desired location of labels on specific types of transformers and step-voltage regulators, and performance requirements of the bar-code labels. To the extent possible, industry standard bar-code specifications and te
29、st methods are described. Use of this standard will promote standardization and uniformity in the use of bar-code labels on distribution transformers and step-voltage regulators.

Overview 1.1 Scope This standard sets forth bar-code label requirements for over
34、head, pad-mounted, and underground-type distribution transformers and step-voltage regulators. Included herein are requirements for data content, symbology, label layout, print quality, and label life expectancy. This standard assumes the existence of central transformer databases within utility com
35、panies so that bar-code labels need only carry basic transformer identification data. 1.2 Purpose The purpose of this standard is to promote standardization and uniform use of bar-code labels on distribution transformers and step-voltage regulators when specified by the user. In the longer term, it
36、is hoped that the bar codes provided as a result of this standard will serve as an integral part of electrical utility material and information management systems.

40、poses of this document, the following terms and definitions apply. The IEEE Standards Dictionary Online should be consulted for terms not defined in this clause. 5ASCII: The code described in ANSI INCITS X3.4 B16, using a coded character set consisting of 7-bit coded characters (8 bits including par
41、ity check), used for information interchange among data processing systems, communications systems, and associated equipment. The ASCII set consists of control characters and graphic characters. bar: The darker element of a bar code. bar code: An array of rectangular marks and spaces in a predetermi
42、ned pattern. bar-code symbol: An array of rectangular bars and spaces that are arranged in a predetermined pattern following specific rules to represent elements of data that are referred to as characters. A bar-code symbol typically contains a leading quiet zone, start character, data character(s)
43、including a check character (if any), stop character, and a trailing quiet zone. bidirectional bar-code symbol: A bar-code symbol format that permits decoding of the contents whether scanned in one direction or the reverse direction. character: A letter, digit, or other special form that is used as
44、part of the organization, control, or representation of data. A character is often in the form of a spatial arrangement of adjacent or connected strokes. 1ANSI publications are available from the Sales Department, American National Standards Institute, 25 West 43rd Street, 4th Floor, New York, NY 10

48、characters that are available for encoding within the bar-code symbol. check character: A calculated character often included within a bar-code symbol whose value is used for performing a mathematical check of the validity of the decoded data. code density: The number of characters that can appear p
49、er unit of length. discrete bar-code symbology: A bar-code symbology where the spaces between characters (inter-character gap) are not part of the encoding scheme. interpretation line: A human-readable interpretation of the bar code that is clearly identifiable with the bar-code symbol that shall represent the encoded characters. inter-character gap: The space between the last bar of one character and the first bar of the next character, which separates the two adjacent characters. Syn: inter-character space. inter-character space: See inter-character gap.
